Appreciate the concern;just posted a fullish update on the "another birthday" posting of April 20, 2014 - seemed appropriate - upshot is have "scale-hopped" to "NZ48".

On your conundrum re interesting NZR yards, I suggest you look on the Guild website at the reproductions of the yard/station drawings from the 1950s issues of the Journal - several offer real possibilities as to recreation in NZ120.

The NZMR Guild web link is to "journal reprints" - there are some 22 plans so far, including Picton, Onehunga & Foxton with wharves; alos Lincoln ( big Y), Kurow, Ngaio, Cromwell etc - a challenge to get that pencil and paper out and mix & match;
